Im looking at purchasing a new Holland 640 round baler. I have a early model 3020 john deere diesel to pull it with. My question is for the buzzer alarm how will I need to wire it up to work with my tractor. Can I run it straight off my battery? thanks
 

Should be two wires? You can connect direct to battery or starter lug. Should have an inline circuit breaker or fuse to be safe.
 
Connect the buzzer to 12 volts. Whatever that means for your tractor. If you have 2 12 volt batteries and a 24V system, connect to one battery, posistve and negative. If you have two 6 volt batteries and a 12 volt system, connect at the positive terminal of the battery whose positive connection goes to the starter, and the ground to the tractor's chassis.
 

Ditto what Rick stated. If buzzer happens to draw much current on the 24 Volt system you're liable to run into a problem getting generator to charge the battery that buzzer is attached to if that battery voltage gets much lower than the other battery that has no buzzer attached.
 
640 is an earlier version of my 644. Keep your chains lubed real good and grease it fairly often and it will last a long time. Mine has been pretty much bullet proof for about fifteen years now. It will burn some twine!
 
I had a 644 when they were new. You say "it will burn some twine." The amount of wraps of twine is adjustable. Is yours set to put the wraps close together so it will use more twine?
 
By being a twine burner, I mean that it is fast for a twine wrap baler. I'm putting on, I think, some 20 wraps, and it will do 24. But I had a NI 484 before this one, and it took over two minutes to wrap and eject a bale. The 644 with the autowrap is about thirty seconds. Just in time savings, the machine can make quite a few bales more in a day because of it.
